UltraChrome Matte-Black-based FS/Piezo inkset
2002-11-27 by Paul Roark
I just mixed a batch of FS/Piezo-compatible ink based on the UltraChrome Matte Black ink. This might be about as pure a carbon set as we can get -- and it's warm. The mix is C=26% K, M=26% C, Y=43% M. I used standard MIS clear base. The resulting densities of the midtones are very close to the original PiezoBW, and, not surprisingly, the tone is not unlike the old PiezoBW or MIS quads after they warmed up (or turned brown, depending on your perspective). The "UC-MK-FS" inkset prints almost perfectly on EAM with the Piezo driver and the EAM profile. The 100% patch density is 1.63 with the Piezo driver (it is still fresh, so it may be a bit darker). With the Epson driver 100% = 1.68. The 50% patch with the Piezo driver reads as follows: Cyan = 0.61, Magenta = 0.65, Yellow = 0.67, Visual = 0.63. This compares to the new PiezoTone Warm-Neutral readings of: C = 0.66, M = 0.67, Y = 0.69, V = 0.66. It'll be interesting to see how this inkset's fade performance compares to the PiezoTone inks.
